Abstract

The objective of this thesis is to analyze the effect of the transformation in the habitat that postfire salvage logging supposes on birds in Mediterranean pine forests, at different levels: species, community and ecosystem, focusing on the bird-mediated seed dispersal process. Salvage logging with commercial purposes is the main factor that determines the species composition after a fire, with the substitution of forest birds by open-habitat species, some of which hold an unfavourable conservation status in Europe. On the other hand, wood debris piles built by non-profitable burnt wood favour the presence of seed disperser frugivorous birds, and these structures show more seed dispersal than other microhabitats, and a higher abundance of bird-dispersed plants, so that it is recommendable to build them in managed burned forests.
